3.1 INSTALLATION PLANNING GUIDELINES
This section provides information necessary for planning the installation of
RM500/RM500R radio set.
3.2 GROUNDING
Failure to provide proper grounding will degrade system operation and cause RF voltage
to be present on the equipment chassis. A serious hazard to personnel or equipment could
result.
Wide copper straps, as short as possible, must be used for grounding. These straps must be
clamped or bonded to a reliable, low-resistance grounding system.
3.3 POWER REQUIREMENTS
The RM500/RM500R requires AC power at a nominal voltage of 110 or 220 VAC, 50/60
Hz. The RM500/RM500R will automatically select the appropriate voltage range. The AC
power consumption during high-power transmission is up to 2 kW.
A suitably rated circuit breaker must be used to protect the supply line to the
RM500/RM500R. It must also enable disconnection of supply voltage during installation
and maintenance.
3.4 COOLING
RM500/RM500R units are cooled by two internal fans. Air is taken in through the front
panel vent, and discharged toward the rear. Therefore, make sure that sufficient free space
is available around the equipment to enable free air flow.
Do not stack equipment units: leave at least 1U free above and below the
RM500/RM500R.
3.5 INSTALLATION DATA
The RM500/RM500R are intended for installation in 19 in. racks. The equipment has
front-mounted brackets for attachment. To provide convenient access during maintenance,
the RM500/RM500R may be installed in a sliding drawer or on slides capable of
supporting the equipment weight.
Make sure that sufficient rack space is available for installation of optional items if
necessary, for example, the 1U high PreSelector/PostSelector (PPS).
The rack must be connected to a reliable, low-resistance grounding system.
Sufficient front and rear clearance is required to permit convenient access to front and rear
panels, as well as for removal and installation of equipment units, connection of cables,
and maintenance.
